中国的能源体系正在面临一场革命,源自三个因素:能源供给安全、雾霾治理和应对气候变化。能源革命的核心是两个替代:通过非化石能源替代化石能源,形成以可再生能源为绝对主体的电力系统,通过电力替代石油和煤炭,形成以电力为枢纽的能源结构。这两个替代的核心是大幅提高可再生能源发电的规模。由于分布式发电的随机性、波动性、间隙性等特点,使得电网负荷峰谷差加大、安全运行稳定性降低、供配电效率减小、电能质量问题更加严重,从而导致电网接纳分布式电源的能力受到限制。在
China’s energy system is facing a revolution that originates from three factors: energy supply security, haze governance and climate change response. The core of the energy revolution is two alternatives: the replacement of fossil energy with non-fossil energy, the formation of an electric power system with absolute energy as the main body, and the replacement of oil and coal with electricity to form an energy structure with electricity as the hub. The core of these two alternatives is to substantially increase the scale of renewable energy power generation. Due to the characteristics of random generation, volatility, and interstitiality of distributed generation, the peak load and load difference of the power grid is increased, the stability of safe operation is reduced, the efficiency of power supply and distribution is reduced, and the power quality problem is more serious. As a result, the power grid receives distributed distribution. The power supply is limited in its capabilities. in
